Managing Kubernetes objects

With Podman Desktop, you can easily transition from containers to Kubernetes and deploy a local Kubernetes environment with necessary objects. As a developer, you have the ability to:

  • Manage your application resources visually.
  • Configure the following Kubernetes objects:
    • Node: Use this object to set up a node on which the necessary pods can run within a kubernetes cluster.
    • Deployment: Use this object to create necessary pods for execution and scale the number of pods.
    • Service: Use this object to expose your application to users and define policies for application access.
    • Ingress: Use this object to define routing rules and manage user access to the services running in a Kubernetes cluster.
    • PersistentVolumeClaim: Use this object to request PersistentVolume resources for storage and define volume access modes within your Kubernetes cluster.
    • ConfigMap: Use this object to to define non-sensitive configuration data for initializing or executing your application.
    • Secret: Use this object to store and manage sensitive data, such as passwords, OAuth tokens, and SSH keys for your application.
  • View and analyze real-time information about the connection status of the resources configured within the cluster.
  • View the dashboard for analyzing object metrics and reading Kubernetes articles and blog posts.
  • Get resource details using the Summary and Inspect tabs.
  • Edit and apply configuration changes directly using the Kube tab.
  • Select multiple configuration files and apply them to your cluster in a single step.
  • Configure port forwarding for a Kubernetes service and view the port forwarding details.

Verification​

  1. View the created object:

    • View the Pod object on the Pods component page.
    • View the other Kubernetes objects on the related object page. For example, if you have created a Node object, you can view it on the Kubernetes > Nodes page.

  2. Optional: Click the name of the object to view its detailed summary. summary tab
